[0002] Bulk solid waste treatment is one of the serious environmental challenges facing the world today. Therefore, there is an urgent need to find efficient, economical and environmentally friendly solid waste treatment methods. Among these solid wastes, carbide slag is a hazardous waste. Due to its strong alkalinity and the presence of toxic substances such as sulfides, it is produced in large quantities and has a high concentration of toxic and hazardous substances, which poses a serious threat to the environment. In addition, the stacking and treatment process of carbide slag may lead to pollution of air and water resources, further escalating environmental risks.

[0003] To solve these problems, carbide slag can be treated by solid waste mineralization. This process includes stirring the carbide slag and introducing carbon dioxide gas to promote the complete reaction of the carbide slag and convert it into a stable and harmless substance. These products can be safely sealed, and the product calcium carbonate can also be used in the manufacture of building materials and even as a high-value-added additive. This not only helps to reduce the harmfulness of carbide slag, but also provides a sustainable solution for resource recovery and waste reduction, promoting the goals of environmental protection and sustainable development.

[0004] However, the existing carbide slag solid waste mineralization device has poor mineralization efficiency due to problems such as poor gas flowability, incomplete reaction of carbide slag, and cannot perform solid waste mineralization on carbide slag well. Utility Model Content

[0032] A transmission motor, the transmission motor is arranged above the transmission shaft, and a power gear is arranged on the transmission motor, and the power gear can mesh with the first transmission gear or the second transmission gear, and can drive the first transmission shaft or the second transmission shaft to rotate through the first transmission gear or the second transmission gear alone, and can also drive the first transmission gear 21 and the second transmission gear 22 to move synchronously;

[0033] The stirring blade 4 is arranged inside the silo 7 and is provided with a through hole. The stirring blade 4 is connected to the transmission shaft 1 through a hollow connecting rod 5. The connecting rod 5 is also connected to the outside of the silo 7. The gas can enter the stirring blade 4 through the connecting rod 5 and enter the silo 7 through the stirring blade 4, thereby solving the problem of insufficient gas in the silo 7 during the mineralization process.

[0034] In a preferred embodiment, a movable component 41 is provided at the upper end of the stirring blade 4, one end of the movable component 41 is fixedly connected to the annular bridge 3, and the other end is movably connected to the upper end of the stirring blade 4, so that during stirring, the stirring blade 4 and the movable component can produce relative rotation, thereby changing the inclination angle of each stirring blade 4 during stirring rotation, thereby achieving the ability to enhance the stirring effect.
